The RA107 powered by the RA807E was successfully introduced their 2007 spec engine before the 2006 season closed.

Honda chiefs are convinced that their RA807E engine will enable the team to achieve regular wins throughout the 2007 season and drive for a serious attempt at the championship title, as well as the constructors title. The problem suffered in 2006 with straight-line speed has not dampened the teams optimism. Button and Barrichello jointly complained on the lack of top speed on the straights last season.

Both senior technical director Shuhei Nakamoto and engine project leader Kazuo Sakurahara are however convinced that the lack of straight-line speed was simply due to the RA106 suffering from high drag.

Without saying as much, Nakamoto seems convinced the RA807E Honda engine is easily the best engine of the field. Many fans of Honda, and indeed critics, have openly said as much.

Unveiled in an all-black paint scheme, Honda F1 racing and its two RA107 cars look to be the dark horses of this year's championship. Last year Button went through the field from fourteenth to score his first ever win. With that exception, no other team apart from Renault and Ferrari scored a win through the entire season. It looks like Honda unveiling their car without a paint-scheme will have others on edge as to what other last minute surprises they will unveil.

And the fact that the team homologated their 2007 engine after Suzuka, with a power unit that included parts originally intended to only appear in an all-new 2007 engine, has left them bullish for next season.

Sakurahara said: "Honda started to show its true potential in 2006 after the German race. On the engine development side, the first part of the season involved repeated trial and error using the data arriving from the circuits.

"During the latter half of the season, we started to yield results as we understood how we could use the V8 engine during the race through the analysis of data accumulated during the first half of the season.

"It was a turbulent year going through the development of an all-new V8 engine and having to cope with the challenge of homologation for 2007, but we were encouraged by the fact that we were able to end the season on an upward curve with the results that were seen at both Suzuka and Interlagos."

Sakurahara claims that most of the team's engine failures over the course of the season were the result of poor quality control rather than out-and-out design failures.

"In the first season we encountered a total of seven engine failures in the course of the 18 Grands Prix weekends, all of which were reciprocation-related problems," he said.

"Many of them were caused by uneven quality of the parts affected by vibration in the crankshaft area. The quality of the parts had never been a problem with V10 engines. As a result we had to improve quality control of the parts for (the) V8 engine."
